EETALLEC SHEATHING.

To all whom ii may concern.'

le 1t known that l, Lans J. Brac. a citizen oi the United States, residing at Chi' cago, in the county of Cook and State et illinois, have invented certain ncp and useiul improvements in Metallic lSlieathing, oit which the following is a specilication.

The sheathing of this invention is intended more particularly for use in covering car bodies; and the object ot' the invention is to provide a sheathing which may be applied 'to the car body, or other structure, in sections, and individually secured thereto in such manner as to proride a plurality of independent air spacesbetween the walls of' the sheathing, and to provide tinished sur i'aces on both sides of the sheathing. The sheathing of the present invention so formed that the attaching means, whereby the sheathing is secured, willbe hidden in the completed structure, which renders the sheathing peculiarly adapted for use on passenger cars in which it is desirable to simulate the appearance of wood.

In thel drawings Figure l is a perspective view of a section of sheathing embodying the present invention; Fig. 2 a longitudinal sectional view of the same, showing the inode of attachment.; and Fig 25 a section of sheathing attached to a curved surface.

The sheathing proper comprises a plu rality ot sections of substantiall)r Si shape. each of the sections comprisingl a pair oi outer walls l ollset with respect to one another and connected by means ot a diagonally extending intermediatewall The ontei walls terminate in oppositely disposed inwardly extending end walls` (5, which are pa allel with the intermediate wall 5, and extend obliquely with respect. to the outer walls. 'lhe end walls terminate in revcrsely turned tlanges 7, and the. end walls (i are slightly shorter than the intermediate wall. so as to bring the flanges 7 into position to contact. the inner angles on opposite sides of the connecting cross 'all of the companion section of sheathing. The sheathing is adapted-for attachment to anysuitable frame or surface by means of bolts or rivets S which are entered through the main walls of the sect-ions of sheathing. l

In use the end section of sheathing is secured in place by means or" the bolts or rivets referred to,after which the next adjacent section of sheathing 'is applied by Specification of Letters Patent.

interlocking it with the first section in such manner as to bring the obliqucly disposed end wall into 'register with the overhanging vall (i of the section liri't applied. `With the parts thus positioned the obliquely disposed end wall of the tirst" applied section will engage the obliquely disposed cross Wall of the section last applied, and this infterlocking or telescoping or the parts into one another serves to rigidly secure the sections of sheathing to one another, and at lthe saine time permits each section to be individually tastened by a bolt or rivet which will he hidden by the application of the nextsuo ceeding section. l O locked atlord air chambers or spaces within the sheathing which are highly desirable in that they serve to insulate against heat and cold and to protect the inner surfaces of the. sheathing against the -action of the elements.

lThe construction is one which is uniform on both sides, so'that a finished surface will be presented on either side, which is desirable in certain forms ot car construction. The channeled formation of the sheathing, as a whole, greatly adds to the strength of the sheathing, and the provision of parallel seams or joints gives to the sheathing, as a whole, the appearance ot' wooden sheathing, so thatl cars provided with the metallic sheathing of the present invention cannot be distinguished from wooden cars of ordinary construction.

What I clamas new and desire to secure by Letters Patent is:

1. A metallic sheathing comprising a plu,- ralit'y et sections ci substantially 55 tor-mation, each of the sections comprising outer 'alls ojt' equal width offset with respect to one another and connected by an oliliquely j extending intermediate wall, Vthe outer walls terminating in obliqnely extending end walls, t-he sections being inter-locked with one another in position to bring the end walls ot one section into register with the intermediate 'alls of the next adjacent sections, and fastening means, as bolts, entered through the side wallson one side of the sheathing, substantially as described. l

2. A metallic sheathing comprising a plurality of sections of substantially S formation, eaclrof the sections having side-walls offset with respect to one another and co1 'i nected-by means of the obliquelyextend The sections thus inten" intermediate Wall, the side Walls terminating in inwardly and obliquely' extending end walls terminating in reversely extending flanges, the Sections being interloclied by bringing the end Walls of one section into register with the intermediate Walls of the nextI adjacent sections, and fastening means, as bolts, enteredvthrough the side Walls on one side of the sheathing, substantially z described 3. A metallic sheathing comprising a plurality of sections of substantially S forniation, each of the sections comprising outer Walls offset with respect to one another, and connected by means of an intermediate Wall so disposed as .to provide an o'verhanging shoulder in conjunction with one of the side walls, the side Walls terminating in inwardly extending end Walls having a formation to closely engage with the intermediate Walls.

ot the adjacent sections, and underlie the shoulders formed by such intermediate Walls and interlock therewith, and fastening means, as bolts, entered through the side Valls on one side ot' the sheathing, snbstan- 25
